IDPF Working Group Improving on EPUB Format for E-books

With the steady increase in e-books sales and the growing demand from consumers for this format, many publishers have had to adjust their business models and production processes to provide their books as e-books. According to May sales figures released this week by the Association of American Publishers and the International Digital Publishing Forum (IDPF), e-book sales increased nearly 163 percent for the month, and year-to-date e-book sales increased 207.4 percent over the same period last year.
